An icon of the 1990s, Casio was one of the first companies to successfully brand itself in the youth market, becoming a symbol of the link between fashion, music and sports. One of its most popular models, the G-Shock, has endured the test of time and can still be seen on the wrists of cool young teenagers all over the world. In fact, Japanese retailer atmos has just teamed up with Casio to collaborate on a special edition G-Shock DW-6900 model. Priced at ¥18,900 (approximately $230 USD), the watch will be available for purchase exclusively through atmos starting in August.
